A roaring sound from all directions prompted us to look out on a moonless night. We saw 5-8 red lights maybe 1/2 to 2 miles away in the sky at about an angle of 35 degrees. The lights were stationary and then some moved and one rose up a bit to make us wonder if it was somekind of fireworks. Then they seemed to change to white lights, smaller, and more of them - the white lights moving and changing position. They then disappeared. The noise slowly ended. About fifteen minutes later white lights could again be seen. The noise resumed at a lower volume and then two white lights moved from west to east and then back east to west at a constant speed and seperation between the lights finally disappearing to the west as the volume faded.
